What is Ars Caelum?

2 parts

Ars Caelum adds a set of rituals that you unlock through the Ars Nouveau questline. This pack ships Ars Caelum 3.0.0 for Minecraft 1.21.1, so everything here is based on that version.[1][2]

The mod is a good fit if you're already working with Ars Nouveau magic and want to push your rituals further. The quest book puts every Ars Caelum ritual in the Ars Nouveau chapter, and each of those quests comes after the Ritual Brazier quest. So you'll want a brazier set up before you start on these.[2]

The rituals the quest book covers

Most of the rituals are island conjuring rituals, each with its own theme. The quest book has you obtain these ones: Conjure Island: Village, Conjure Island: Geode, Conjure Island: Cascading, Conjure Island: Flourishing, Conjure Island: Deep Dark (shown in game as Deep Dark), Conjure Island: Blazing, Conjure Island: Vexing and Conjure Island: End Portal.[2]

Three more rituals sit alongside the islands: Summon Guardians, Sedimentation and Mana Regeneration. Each has its own quest in the same chapter.[2]

Where it fits in progression

These quests all branch from the Ritual Brazier quest, which makes Ars Caelum an optional extension of the Ars Nouveau path rather than a separate stage of the pack. The sources don't show it on the ATM Star path, so you shouldn't need it for that goal.[2]

Unverified The quests are untitled, and the sources don't describe what each ritual does in detail, how it is crafted, or what it costs. Check the recipes and the in-game tooltips for those before you plan around any of them. This site does hold All the Mods 10: To the Sky's own recipes, read from the pack itself: look the item up in the item browser.

How do you get started with Ars Caelum?

4 parts

Ars Caelum adds a set of rituals to the pack. Each one is a ritual item you craft, and each has its own quest in the Ars Nouveau chapter, which comes after the Ritual Brazier quest. So your first job is getting a Ritual Brazier going, then working through these items.[2][3]

The sources don't give an official order, so what follows is my suggested order, built around what each ritual does.[2][3][4]

Start with Sedimentation

Sedimentation converts four nearby water sources and produces cobblestone on the last source it consumes. Augment it with Deepslate and you get deepslate instead. Its quest is a quest in "Ars Nouveau".[2][4]

SedimentationMod recipe

Crafting Shapeless

Recipe id: ars_caelum:ritual_sedimentation

Then Mana Regeneration

Mana Regeneration grants mana regeneration to all players nearby. Its quest is a quest in "Ars Nouveau".[2][4]

Mana RegenerationMod recipe

Crafting Shapeless

Recipe id: ars_caelum:ritual_mana_regeneration

The biome island rituals

The Conjure Island rituals are the big ones. The biome islands each need a full jar of Source to begin, and they should be performed at least 14 blocks from any other block, so give yourself plenty of empty space before you start.[4]

Specialty islands and Guardians

Save these for later. Conjure Island: Village conjures an archwood village island with several villagers. Its quest is a quest in "Ars Nouveau".[2][4]

Conjure Island: VillageMod recipe

Crafting Shapeless

Recipe id: ars_caelum:ritual_conjure_island_village

Watch out: Summon Guardians brings waves of Guardians, and adding a Sea Lantern summons an Elder Guardian, so only add it if you want that fight.[4]

How does Ars Caelum work?

3 parts

Ars Caelum works through rituals in this pack. The sources I have cover what each ritual does and how its item is crafted. They don't describe machines, multiblocks, power, fluid handling or automation, so I'm not going to guess at those.[3][4]

Island rituals

Most of the island rituals need a full jar of Source before they begin. The exception in the descriptions is the village ritual, which doesn't mention it. The island rituals also carry a placement warning: perform them at least 14 blocks from any other block, so pick an open spot. The End Portal ritual words it more strictly and says it must be performed 14 blocks away from other blocks.[4]

Utility rituals

  • Sedimentation converts four nearby water sources and produces cobblestone on the last source consumed. Augment it with Deepslate to get Deepslate instead.[3][4]
  • Mana Regeneration grants mana regeneration to all players nearby.[3][4]
  • Summon Guardians summons waves of Guardians. Augment it with a Sea Lantern to summon an Elder Guardian.[3][4]
Watch out: The Summon Guardians ritual spawns hostile mobs, so only start it when you're ready to fight. The Elder Guardian version needs the Sea Lantern augment.[4]

Crafting the ritual items

In this pack every ritual item is made with a shapeless crafting recipe. The ingredients are mostly Ars Nouveau archwood logs and saplings, plus things like diamonds, ender eyes or blaze rods. Here are the exact in-pack recipes.[3]

How do you progress through Ars Caelum?

2 parts

Ars Caelum doesn't have a tier ladder of its own in this pack. Its progression runs through the Ars Nouveau quest chapter, where every Ars Caelum ritual has its own quest. Each of those quests comes after the Ritual Brazier quest, so you need to get through that one first.[2]

The quest tasks are simply to obtain the ritual item. All the rituals are crafted as shapeless crafting recipes, so you don't need any special crafting station to make them.[2][3]

Island rituals

Eight of the rituals conjure islands. Each has a quest whose task is to have the matching item.[2]

Here are the in-pack recipes for the island rituals. The Village ritual asks for the most ingredients of the whole set, so expect it to be the biggest crafting job.[3]

Utility rituals

The other three rituals follow the same pattern, each with a quest after the Ritual Brazier: a quest in "Ars Nouveau" for Summon Guardians, a quest in "Ars Nouveau" for Sedimentation, and a quest in "Ars Nouveau" for Mana Regeneration.[2]

Unverified The quests are untitled and have no description text in the sources I have, so I can't confirm a recommended order, what each ritual does when performed, or how it is activated at the Ritual Brazier. Check the quest book in-game for that.

How does Ars Caelum work with other mods?

3 parts

In this pack, Ars Caelum connects almost entirely to Ars Nouveau. The Ars Caelum recipes that use other mods' items are all shapeless crafting recipes built around Ars Nouveau items. Some also mix in vanilla items and shared item tags.[3]

The quest book follows the same link. The Ars Nouveau chapter has one quest per Ars Caelum ritual, and each one comes after the Ritual Brazier quest. The task in each quest is the ritual item itself.[2]

Rituals and their quests

Here is every Ars Caelum ritual that has an in-pack recipe, along with the Ars Nouveau chapter quest that asks for it. The quests are untitled in the quest data, so they are listed here by ID.[2][3]

Archwood is the common thread

Ars Nouveau archwood shows up in every one of these recipes, and the colour changes from ritual to ritual: Blazing Archwood Log, Cascading Archwood Log, Flourishing Archwood Log and Vexing Archwood Log. Several of the island rituals also take archwood saplings, such as Blazing Archwood Sapling. To craft the full set of rituals you need a way to get every archwood colour.[3]

Other Ars Nouveau materials show up as well. Mana Regeneration uses Abjuration Essence, and Sedimentation uses Frostaya.[3]

Recipes worth checking

  • any source storage block
  • any diamond gem

Summon GuardiansMod recipe

Crafting Shapeless

Recipe id: ars_caelum:ritual_elder_summon

Tip: Several of these recipes ask for any item in a shared tag rather than one specific item, such as any diamond gem or any blaze rod. The Mana Regeneration recipe is a mix: it names Blaze Rod directly but takes any diamond gem.[3]

Which All the Mods 10: To the Sky quests use Ars Caelum?

2 parts

All of the Ars Caelum quests in this pack sit in the Ars Nouveau chapter. Each one has a single item task: you hand in one of the mod's rituals.[2]

Every one of these quests comes after the Ritual Brazier quest, so the Brazier is your gate. Once you're past it, the ritual quests all hang off that same point, and the quest data lists no ordering between them. The quests have no titles in the pack files, so they're identified by their IDs below.[2]

The island rituals

Most of these quests are for Conjure Island rituals, each one a different island type.[2]
